## TL;DR

This paper presents seven new draft genomes of Kluyveromyces marxianus from South Africa, expanding our understanding of its genetic diversity beyond dairy-related uses.

## Contribution

The study provides new genomic data for K. marxianus strains from non-dairy environments in South Africa.

## Key findings

- Seven draft genomes of K. marxianus were sequenced from South African isolates.
- The genomes expand the known genetic diversity of this yeast species.
- The study highlights the potential of K. marxianus for industrial biotechnology beyond dairy.

## Abstract

Despite its recognized potential for industrial biotechnology and lactose-based fermentations, the genomic diversity of the yeast Kluyveromyces marxianus remains underexplored, especially in non-dairy contexts. Here, we report the draft genomes of seven strains isolated from South Africa, expanding the known genetic diversity of this versatile species.
